I am in shock and still crying as I write this.  My friends Amy and Jonathan lost their dog Mesa to a heart attack on the drive to Scottsdale.  I will never forget the first time I saw them run as a team.  It was my first agility trial ever, at some random park in Tucson and I could feel the energy from their run just standing outside the ring.  Mesa is to agility what dogs are to barking.  I am sad for the Hanridge family and the agility community, things without Mesa just won't be the same.  Please hug your dog.  And try to be the best team mate you can be, and run every run like it is your last, because you never know, it just might be.
